What is Web Browser in Computer

Web Browser

An application used to visit webpages is called a web browser. The browser gets its files from a web server when a user requests a page from a specific website, and then it shows the page on the user's screen.

A Web browser is a client program that represents the browser user in requests made to Web servers across the Internet using Hypertext Transfer Protocol. The File Transfer Protocol (FTP) and email are supported by the majority of browsers; but, specialist client programs are more widely used and a Web browser is not necessary for these Internet protocols.
